Check Digit Verification of cas no

The CAS Registry Mumber 1469876-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,6,9,8,7 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1469876-41:
(9*1)+(8*4)+(7*6)+(6*9)+(5*8)+(4*7)+(3*6)+(2*4)+(1*1)=232
232 % 10 = 2
So 1469876-41-2 is a valid CAS Registry Number.

Asymmetric synthesis of α-(heteroaryl)alkylamines and α-amino acids via nucleophilic 1,2-addition of lithiated heterocycles to aldehyde SAMP-hydrazones

Enders, Dieter,Del Signore, Giuseppe,Raabe, Gerhard

, p. 492 - 518 (2013/08/23)

The asymmetric synthesis of α-(heteroaryl)alkylamines was accomplished by employing a diastereoselective nucleophilic 1,2-addition of lithiated aromatic heterocycles to aldehyde SAMP-hydrazones, followed by BH 3·THF or SmI2 promoted removal of the chiral auxiliary. The CBz or benzoyl-protected amines were obtained in good yields (40%-78%) and excellent enantiomeric excesses (ee = 88%-99%). The methodology can be applied to the synthesis of highly enantioenriched α-amino acids (ee = 90%-99%). TUeBITAK.
